Have you ever wondered how CDs were invented? The truth, however, is that the inventor of the compact disc is time 
and again disputed as it’s argued that the invention of a compact disc was a 
role played by several people.

However, the most attributed inventor is 
James Rusell. In 1965, James Rusell was inspired by a revolutionary idea as he 
made a rough sketch on paper, an ideal music recording system which would 
replace vinyl records. Rusell’s idea was to come up with a system that could 
record and replay sounds without requiring physical contacts between parts.

Development
Rusell struggled to attract investors, but 
with time Sony and a few other companies recognized the potential in Rusell’s 
idea and purchased licenses of the CD-ROM technology. The support of large 
corporations further improved the idea to ensure it was ready for market.

It was in 1978 Polygram when a division of 
Philips suggested polycarbonate as the material to make CDs. There were other 
decisions made at this time such as the disc diameter (115 mm) and the type of 
laser to be used. Additionally, it was decided that data on a compact disc 
would start at the center going spiral outwards to the edge.

In the following year, Europe and Japan 
hosted prototype CD system demonstrations where Sony agreed on terms to join into collaboration 
with Philips. The disc diameter was slightly changed from 115 mm to 120mm which 
allowed for 74 minutes of playback at a sampling rate of 44.1 kHz and a quality 
of 16-bit audio.

Announcement
The CD was first announced 15 years after 
the invention by Philips on May 17, 1978. The announcement came with the 
proposed standards that were agreed between Sony and Philips. They made the “Red 
Book”, containing the technical specifications for all CD-ROM and CD formats. 
The collaboration between Sony and Philips ended, however, as the two companies 
had produced products ready for 1982.

CDs are made from a thick polycarbonate 
plastic(12 mm) weighing around 16 grams. There’s a thin layer of Aluminum that’s 
applied on the surface so that it appears reflective. It’s then protected by a 
thin layer of lacquer. Screen printing is the process used to manufacture CDs.

Introduction
The first CD audio player was released to 
the market by Sony in October 1982. The CDP-101 surfaced on the market in the 
same year, and the usage of CDs across Japan and Europe became widespread. At the 
time, Compact discs were ridiculously expensive with each going for $30. They 
were manufactured by only two facilities in the world which made the process 
tedious. Fortunately, there were six factories to do the job, and the price 
dropped significantly.

In the mid-1980s, portable CD players were 
introduced, but it’s until 1990s when they became popular. Other manufacturers 
followed Sony footsteps until the CD finally became the industry’s standard 
format for video and audio data.

Vinyl records have come back in style. In fact, millions of people have been picking up these wax based audio releases. A lot of arguments have been brewing on the internet about why. There are a lot of factors that can be considered. Even though some may find some reasons obvious, others will point towards the hipster movement. One thing is for sure, the struggling independent record stores of the past, are starting to revitalize based solely on new and used recordings on this option. Looking at the following reasons, you will see why this is not just a trend.

It Is Cost Effective

Digital libraries fade away when hard drives crash. Compact discs are nothing more than coasters for people. But a large format LP? That is a tangible commodity that can cost you less than some of the releases in mp3 formatting. Not only that, you can get a download code, compact disc, and the wax pressing for less than what it used to cost to just purchase the album straight away. Not only that, buying used or vintage releases can be quite inexpensive, and as low as 99 cents in many cases, (though you might be happy to find out that some of your parents old records can be worth quite a lot.) Just one look through any major independent retailer that stocks new and used options will give you blasts from the past at a low price. The luxury of digging through crates is no longer just for DJ’s it’s for anyone.

It Sounds Better (At Least In Theory)

It doesn’t sound better based on wavelength. However, audiophiles will argue about how it is a perfect way to listen to music. It may be nostalgia, it may be a larger sound, or it may just be that mp3 standards are so awful and truncated that when someone hears vinyl recordings, they are impressed. There are certain nuances that listeners cite on classic music offerings that are losses in digital formatting. It’s arguable whether or not it’s perfection, is a matter of the listener’s opinion.

Aesthetically Pleasing

In the end, it looks great. Large format artwork, in most cases, colored vinyl, and a physical item to cherish. There is just something compelling about holding a physical item that screams out that you love music. Whether you are digging in crates for some classic hip hop, or you have purchased the latest 180-gram vinyl remaster, there is no doubt that you are a person that loves music enough to pay money to get it. Try pirating a vinyl record, try sharing it and copying it, and you will see that this format is truly for lovers of music.

There are countless other reasons why vinyl records are becoming popular again. Last year alone, they sold millions upon millions of copies. Not only are new releases coming out in the format, the classics are getting redone, and put out in limited options. You may not agree with this sentiment, but they aren’t making a comeback since they never left.
